FRANK A. RYTHER, OF UHICAG(.), ILLINOIS.

CORN-SHOCKER.

SPECIFICATION forming part of Letters Patent No. 764,381, dated July 5, 1904.

Application filed October 2, 1903.

T0 at whom, it near/y concern: Be it known thatI, FRANK A. RYTHER, a citizenof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn-Shockers, of which the following is a complete specification.

Heretofore in this class of machines a windlass operated by manual power has been used to raise the shock from the platform preparatory to swinging it from and depositing it at the side of the machine.

The object of this invention is to provide a device whereby the draft-animals of the machine may be employed to raise the shock from the platform. :To accomplish this, I provide means as set forth in the accompanying drawings, in which Figure l is a rear view .of a corn-shocking machine embodying my improvement. Fig. 2 is a plan view of the same with partsremoved. Fig. 3 is a perspective of the drafttongue and evener of a corn-shocker, show ing the essential elements of my improvement in connection therewith. Fig. 4 is a side elevation of the tongue, showing the improve ment mounted thereon and also a view of the crane and sheaves with a rope connection to the principle of the operation of the mechanism. Fig. 5 is a perspective of the notched retention-bar. Fig. 6 is a detail persective showing the construction of the foot-trip which actuates the pawl controlling the notched retention-bar, and Fig. 7 is an enlarged perspective of this pawl.

While this invention can'be applied to any style of corn-shocking machine,.it is particularly applicable to the type shown in Patents No. 724,515, of April 7, 1903, and No. 734,973, of July 28, 1903.

More specifically stated, the invention relates to connecting a notched bar to the evener 0f the machine, this bar being so constructed that it can be locked or detained in any desired position longitudinally relative to the tongue of the machine, the power for operend of the boom G.

Serial No. 175,434. (No model.)

ating the machine being transmitted from the draft-animals therethrough. The rear endof this bar connects with what would otherwise be the fixed end of the Windlass-rope, the arrangement being such that as the retentionbar is released and the draft-animals advance the machine will remain stationary and the effect of the pull will be applied to raise the shock through the said retention-bar and connecting-rope. As the other end of the rope connects with the Windlass, the shock may be raised by manual effort, if desired.

Only those parts of the machine directly connected with and affected by this improvement will be described herein. For a detailed description of the general construction of this type of machine reference may be had to the patents. cited.

Referring to the drawings, A represents the main frame of the corn-shocker; B and B, the supporting wheels; (J, the rotating shockforming table; D, the gatherers, and E the d raft-tongue.

F designates the shock-forming standard, detachably mounted upon and rotatable with the shock-forming table 0, and is provided with the arms f.

G represents the main standard of the crane,

rigidly secured to the frame of the machine,

and Gr is the boom mounted thereon.

The main standard Gr is supported by the braces g, and the juncture of these braces with the said standard is effected through the casting H. On this casting H is rotatably mounted the casting I, to which is pivotally secured the said boom G. The boom G overhangs the shock-forming table C, the free end there of being substantially vertically coincident with the shock-forming standard F, mounted on said table.

J is a manually operated Windlass supported upon the standard G and the stubbleward braces g and around which" passes the rope J, the said rope extending upwardly over the sheave j, which is secured to the upper end of the standard Gr. The rope extends from this sheave to and passes over one of the double sheaves which is secured to the free Passing down from this sheave the rope engages a movable sheave j As heretofore constructed the rope returned to the free end of the boom G and was made fast thereto. Instead of this construction, however, the previously-fixed end of the rope is returned over the double sheave y", then through a second sheave f secured to the upper end of the standard G, and from there passing to a sheave 3, (see Figs. 3 and at) over which it passes and connects with the draft device in a manner hereinafter described.

As nothing more is claimed in the abovementioned elements, a general description thereof will suffice, it being of importance to point them out only for the fact that they are associated or operatively connected with my improvement.

Referring to Figs. 3 and 45, e and a designate plates or flanges secured to and arranged longitudinally of the draft-tongue E. These plates or flanges form a slot in which pivots a double bell-crank lever having the arms in, k, and L is a notched retention-bar adapted to be received by and moved longitudinally in the slotjust mentioned. In a hook Z, formed on the rear end of this retention bar, is secured the rope J, while the front end of said bar connects with the evener M.

The position of the double bell-crank is controlled by the rod N, which engages the arm of said bell-crank and extends rearwardly to and connects with the foot lever O, as shown in plan view in Fig. 2 and in detail in Fig. 6. This foot-lever consists of a transversely-extending portion which serves as the fulcrum for the lever and the cranked ends which form the arms 0 and 0. To the arm 0 is connected the operating-rod N, while the arm 0 serves as a foot-trip and is within reach of the operators seat. At the free end of the arm 0 is a downwardly-turned end 0 the foot-lever as a whole being so located that this downwardly-turned end 0 will engage the main driving-chain Z) of the machine, as shown in Fig. 2, when the foot-trip is depressed, and when so engaged it operates to lock the machine. A coil-spring 0 on the foot-trip O operates to move the arm 0 rearwardly or in a direction as indicated by the arrow in Fig. 6. On the forward end of the rod N is secured the coil-spring n, which affords a yielding connection between the said rod N and the arm 70 of the double bell-crank.

Secured to the evener M and longitudinally movable therewith is the forwardly-extending member E, consisting, preferably, of a pipe secured loosely to the tongue E by means of the eyebolts 0 6 .To the forward .end of this pipe E is secured the neckyoke of the draft-team by means of the U-bolt 0 the same bolt securing to said pipe a stop 6', which operates to limit the rearward movement of the evener M and the pipe E.

I The operation ofthe .device is as follows: The normal relative positions of the parts constituting my improvement are shown in Fig.

3, where the parts are held in these positions by the coil-spring 0 on the foot-lever 0 operating through the controlling-rod N to depress the rearward armk of the double bellcrank until it engages one of the notches Z on the forward end of the retention-bar L. This effectually locks the evener M to the tongue. When a shock is formed on the revolving platform C and it is desired to remove it, the foot-engaging portion 0 of the foot-trip O is depressed, pushing the rod N forward and compressing the spring m until the arm Zr; is disengaged from its notch in the said retention-bar. In depressing the foot-lever O the hook 0 will be caused to engage the main driving-chain b and lock the machine against further advance until released. The draftanimals are started and their pull, instead of advancing the machine, operates through the bar L and the rope J to lift the shock. from the table. When the shock is lifted to a sufficient height, the operator depresses the footlever until the arm It" of the bell-crank engages one of the notches Z in the retentionbar, in this way locking the retention-bar in its forward position, as shown in dotted lines in Fig. 3. The shock will thus be held suspended above the table, and the operator swings thecrane and shock to a position to deposit the latter at the side of the machine. After the shock has been deposited the crane is swung back and again connected with the platform, the draftanimals backing sufiiciently to permit of the reengagement of the standard with the table, which movement will also bring the retention-bar back to its normal position, and the operator on releasing the foot-trip will permit the bar to be again locked in its normal position. I

It is understood, of course, that the function of the pipe E is to accommodate the forward movement of the neck-yoke secured to the draft-animals, .the stop e limiting the rearward motion of the said pipe relative to the tongue E. The pin Z* in the rear end of the retention-bar L contacting the plates or flanges e and elirnits the forward movement of both the retention-bar and the pipe relative to the tongue, while the pin Z in the forward end of said bar limits the rearward movement of same.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a corn-shocking machine, in combination, a shock-lifting crane, a draft-tongue and evener sliolably mounted thereon, a notched retention-bar connecting said evener with the shock-lifting crane and means'for looking at will the said retention-bar to the said drafttongue thereby preventing relative longitudinal movement of same in onev direction or the other, substantially as described.

a 2. In a corn-shocking machine, in combination, a shock-lifting crane, a draft-tongue, an evener slidably mounted thereon, a retention- IO ment thereof while the forward arm of said bell-crank is adapted to engage the notches on the rearward end of said retent1on-bar and prevent rearward movement thereof, and

means connecting with the third arm of said bell-crank for operating same, substantially 5 as described.
